Environment
Novell GroupWise 8 Support Pack 1 Hot Patch 1
Microsoft Windows 7
Situation
If you run a quiet installation of GroupWise client using /qb (basic GUI), it fails during registration of gwab1.ocx file.
Also other, unattended client install options /passive and/or /qn fail with 1603 error installation (seen if /lv <log> option is enabled).
Resolution
This has been resolved and the fix is available in SP2 of GW8.
Make also sure that you have installed vcredist_x86.exe (can be found under client\win32 directory of the SDD) prior you install a GroupWise client. You can use a quiet install option like:
vcredist_x86.exe /q
Once this is installed on a workstation, you can continue with actual GroupWise client installation.
